Weather Talk: Few Thanksgivings have seen inch or more of snowLast year, today was a rare snowy Thanksgiving Day. Since 1950, there have only been five Thanksgivings with more than 1 inch of snow falling on the holiday.
Although we had already had a few little light snows last fall, the one on Thanksgiving was the first to create icy roads. A bit over 2 inches fell with a strong north wind lowering visibility. And with temperatures going from above to below freezing, the roads became quite slick.
This year, Thanksgiving falls as late as it can – on Nov. 28. Since records began in 1881, measurable precipitation falls on any given November day about 20 percent of the time, but those odds increase as the month progresses.
The period of this month with the highest historical chance of precipitation are the 25, 26 and 27 when nearly 30 percent of those days have recorded precipitation.
This means the later Thanksgiving Day falls, the higher the chance of slippery roads.
